最大孔径 meaning in Chinese
full aperture
maximum diameter of hole
maximum size
Examples
- Filter paper and filterboard - determination of maximum pore diameter
过滤纸和纸板最大孔径的测定 - Compared with host film , thickness and porosity of composite film change not much , while average and maximum pore size decrease , and pore size distribution range become narrow . further more , controlling reaction time can control the content of in - situ transforming fe3o4
结果表明，采用膜相渗透原位化学转化法合成制备的fe3o4 / pvdf复合膜，其膜厚、孔隙率与原来的pvdf基体膜相比变化不大，平均孔径、最大孔径则有明显减小，孔径分布范围变窄，孔径更趋于均匀，膜孔形态更为规整。 - In order to make clear the effects of fe3o4 on composite film structure , the thickness , porosity , average and maximum pore size , pore size distribution of different films are measured . surface morphology is studied by scan electronics microscope ( sem ) . the characterizing results of film micro - morphology showed that pore structure of fe3o4 / pvdf composite film were better than those of pvdf host film
为进一步分析fe3o4的原位生成对复合膜结构的影响，测定了pvdf基膜和复合膜的膜厚；采用干湿膜重法测试了膜样品的孔隙率；采用泡点压力法流体渗透法相结合，对比测试了膜样品的最大孔径、孔径分布及平均孔径；通过扫描电子显微镜（ sem ）照片分析，对比研究了pvdf基体膜和fe3o4 / pvdf复合膜的表面形貌。
